On Two-parameter Dynamical Systems and Applications %R %X In this note some useful properties of strongly continuous two-parameter semigroups of operators are studied, an exponential formula for two-parameter semigroups of operators on Banach spaces is obtained and some applied examples of two-parameter dynamical systems are discussed %U https://jsciences.ut.ac.ir/article_31597_6c28a592f208c684f7b9630194ef5114.pdf
